FIG. 10 illustrates a process of making loop members of various shapes for maximum flexibility and rigidity. In this method a straight wire is pre-bent fully or partially prior to clamping two ends. This pre-shaped loop member is then sewed to a fabric to make a sunshade. Pre-bent wire provides maximum coverage and flexibility possibly to adopt fitment to the vehicles with similar shaped and/or dimension windows. The pre-shaped loop member also can be used to make a sunshade for a house or any other window wherein a substantially rectangular shaped loop member is sewed on a fabric. Pre-bent loop member provides better fitment appearance due to loop member having a naturally bent to match the shape desired prior to clamping of two open ends of the straight strip. As shown in FIG. 10, 1005 is a straight stripe of flexible steel flat wire from which a loop member is made by clamping two ends of the substantially straight strip. Shape 1010 is formed by bending of the partially or substantially straight strip 1005. Another shape 1015 is formed by bending a straight flexible steel flat wire 1005 into 1015. Another shape 1020 is formed by bending substantially straight flexible steel flat wire 1005 into desired shape. The shape can be of any kind to insure best fitment possible. This method of pre-bending metal loop member provides better overall fitment. Once pre-bend to the desired shape; two ends of each of the shapes 1010, 1015 and 1020 is crimped using clamps 1011; 1016 and 1021 respectively which then is sewed upon a fabric.

FIG. 11 illustrates a sizing guidance method 1100. In this method; more than one size of window sunshades are listed under one section 1120 of same make 1105 wherein for each make multiple different sizes are listed for at least two of the vehicle models in the section 1110 with a model year to provide identification of specific vehicle model. In this method the end user do not need to scroll through multiple sizes of the sunshade in order to locate the year make and model of their vehicle.

FIG. 12 illustrates a sizing guidance method 1200. In this method; multiple vehicle models 1210 of the same make are short listed with a year 1215 to identify specific vehicle models with corresponding size 1220 compatible with those vehicle models. In this method different sizes can be listed in one section 1220 that is compatible with identified vehicle by combination of 1210 and 1215. This method helps customer locate the vehicle model in a one chart once they locate the make of their vehicle models and eliminates need for customer to locate the make in more than one size-charts thus makes the compatible size guidance comparatively hassle free and easy. In this type of compatibility information, all vehicle models from the same make are listed under a one section wherein at least two different sizes are recommended for the at least two vehicles listed under the one section. Guidance method 1100 and 1200 has at least two vehicles from same make shortlisted wherein the at least two vehicles are compatible with different window sunshade sizes.

FIG. 13 illustrates a sunshade installed inside a vehicle window providing compatibility method wherein the compatibility of sunshade is based on the height of the loop member 1305 similar to the height of the window 1310 it's being recommended for. The compatibility method also can be based on the adjustable width of the sunshade by partial overlapping and/or extension of the both the loop members as shown in FIG. 1. In this guidance method, both the circles are partially overlapped to fit various width windows. By using this compatibility guidance method for this sunshade; one size can be recommended for various widths of windows. The size-guidance for this automotive interior sunshade also can be based upon the height of the loop member being similar to the height of the window. An automobile interior window sunshade comprising at least one loop member sewed on at least one fabric and compatibility information can be provided wherein different compatible sizes are listed in the same size-chart to provide best coverage possible for any given automobile model. A guidance method also can be based on the height of the loop members. The loop member also can be overlapped to achieve coverage for variety of widths. A guidance method also can be based upon the sunshade's ability to cover various dimensions that provides coverage to the various dimensions of windows. The guidance also can be based on the top and bottom portion of the loop member which is substantially straight and/or arched wherein the distance between top and bottom loop member sides is substantially identical to the height of the window/windshield.

The sunshade mentioned in this invention also can be used for door windows of a vehicle and/or rear windshield/window of an automobile. The sunshade also can be customized and used with any kind of window to block the sun light including house windows. The fabric of the sunshade can be secured by sewing a one side of Velcro on the sunshade and sticking other piece of the Velcro on the window its being placed against to provide better coverage. The guidance chart shown in the FIGS. 12 and 13 wherein the compatibility guidance is provided for a given sunshade's loop member's height being substantially similar to the height of the vehicle's windshield glass. The fabric between two loop members allows extended coverage wherein the extra fabric also provides material needed to overlap both the loop member to fit a narrow width windshield glass of a vehicle. The compatibility guidance provided in this invention can be based on minimum and maximum coverage area of the sunshade by overlapping or extension of the two loop members. In 2 pc sunshade designs wherein two pieces are separate can be overlapped to one another partially and the compatibility recommendation will be based on smallest width of the windshield the shade can fit by overlapping of the two separate sunshade pieces to the widest vehicle windshield by extension of both the loop members of two separate pieces. The height of each of the two loop members in every guidance method needs to be substantially similar to the height of the windshield it is being recommended for.

FIG. 14 illustrates a cross section of configuration in which the flexible steel flat wire 110 of any embodiment shown in figures can be secured onto the fabric 105. The flexible steel flat wire configured loop member 110 is placed onto the fabric 105 keeping one of the two steel enclosure thickness sides and one of two wire thickness sides 112 touching the fabric and other facing into opposite direction. The orientation keeps the two enclosure width sides and two wire width sides 111 perpendicular to the fabric plane. The two flexible loop members 110 is then secured to the fabric 105 with secondary fabric 104 with the two flexible loop members 110 in-between the secondary fabric 104 and the fabric 105. The secondary fabric 104's inner edge 106 is sewed with sewing stitches 107 on the inner side and the outer edge 108 is sewed with sewing stitches 109 on the outer side of the flexible steel flat wire loop member 107. The stress created by the loop member 110 is distributed between two stitches 107 and 109.

The interior window sunshade also can be constructed without pre-bending the flexible steel flat wire. The flexible steel flat wire loop member 110 also can be made by clamping straight wire which turns its shape into round loop due to stress. The round loop then is sewed and guided to make flexible arches or the bypass-bend for the various configurations of the interior window sunshade shown in this application.
